Thousands descended on Cleveland this week to attend the four-day Republican National Convention at Ohio's Quicken Loans Arena. The crowd was composed of delegates, politicians, protesters, journalists, and even some celebrities like boxing promoter Don King. The GOP event comes to a close this evening with a speech by Donald Trump, the party's official nominee for president. Below are a selection of some of the more interesting images to come out of Cleveland.

Yes, wasting water is actually bad for the environment. There are anthropocentric, biocentric, and ecocentric reasons why wasting water is bad.
Anthropocentrically, fresh water is a vital resource for the survival of our population. Seeing as less than 1% of the world's water is freshwater and available for us to consume (not trapped in glaciers), there are limitations that factor into our carrying capacity as a population on Earth including the availability and distribution of freshwater. Different countries are endowed with different stocks of freshwater, and depending on their replenishment rate and usage rate, each has varying degrees of water scarcity that needs to be addressed. Below is a map by World Resources Institute that outlines the water stress by country, with 36 countries displaying an "Extremely High Stress (>80%)," which means that "more than 80 percent of the water available to agricultural, domestic and industrial users is withdrawn annually--leaving businesses, farms and communities vulnerable to scarcity" (World's 36 Most Water-Stressed Countries).
Therefore, wasting water in a country where it may appear water just magically comes out of the tap (i.e. Canada, the U.S., most developed countries), is wasting a precious, vital resource that millions (663 million, according to Water Facts: Facts About the Global Water Shortage) don't even have clean, safe access to.
Furthermore, in places where clean water is scarce, overusing or wasting household water limits the availability of it for other communities to use for drinking, cleaning, cooking or growing--and thus contributes to disease, illness, or agricultural scarcity/starvation.
You could tack on the economic incentive to save water, as it means lower household water utility bills, one of the largest incentives for water-wise individuals or households to conserve water.
Biocentrically, other species rely on freshwater besides humans as a vital component to their survival! Overuse of freshwater in household settings means there is less fresh water for agricultural use (which affects humans on an food scarcity level), but many livestock species rely on freshwater. Also, as we divert more freshwater from aquatic environments to supplement agriculturally, many plant and animal species are threatened or can become endangered. Despite our attempts to separate man from nature, we are indeed part of one ecosystem (the biosphere), and reliant on plants and animals; therefore sharing and properly managing our most precious resource is crucial.
Ecocentrically, wasting water while our demand for water increases (as population and standards of living increase globally), means that we need to supplement for this lack of freshwater by pulling it out of aquifers or groundwater supplies in which their regeneration rate is lower than the extraction rate. This unsustainable practice decreases long term water security and availability.
Furthermore, and almost most importantly, water takes a lot of energy, time, and money to filter and clean so that it's drinkable. Wasting water or overusing household water means you're wasting the energy-intensive process of filtration. The many steps of this process--extraction, transportation, filtration, etc.--require non-renewable fossil fuels and as these resources become depleted, their dangerous by-products such as carbon dioxide build up in the Earth's atmosphere, contributing to your carbon footprint and the Earth's rising temperatures.

An international team of researchers working on the Large Underground Xenon dark matter experiment announced today that they have failed to detect any dark matter particles.…
After years of planning, designing, acquiring materials, developing infrastructure, laying and burying 1,200 meters of pipe, and testing water quality and functionality, the seemingly impossible was achieved: for Colombia's Kogi people, and their related tribes who rely on Jaba Tañiwashkaka, a historically sacred site, an aqueduct that provides access to water for crop irrigation and potable water for consumption is now in place. And thanks to a determined site restoration effort, alligators, nutria, and capybara are only a few of the animals now seen in a wetland previously largely devoid of wildlife.
The Kogi people live on roughly 14.5 million acres in Colombia's northern Sierra Nevada de Santa Marta region. Around the margins of the Sierra Nevada is the Línea Negra, the “Black Line,” a chain of 54 pilgrimage sites sacred to the Kogi and once part of their ancestral territories. Most of the associated sites are not currently under Kogi ownership or control—the Kogi were forced to abandon them due to decades of colonization and violent civil conflict—and many are endangered by poorly planned development schemes, megaprojects, mining activity, and/or illicit crop cultivation.
To address this, in 2012, the Amazon Conservation Team (ACT) partnered with the Colombian Ministry of Culture and the Organización Gonawindúa Tayrona of the Kogi people to purchase the essential section of a coastal sacred site that the region's indigenous communities call Jaba Tañiwashkaka—an area of great environmental and cultural importance.
With the legal consolidation and traditional management of Jaba Tañiwashkaka well underway, thanks in part to additional land purchases, a pressing task has been the construction of a water supply system that allows for the continuous residence of Kogi families in their reclaimed territory and the establishment of small-scale subsistence agriculture on three hectares to sustain the families and authorities who live at or visit the site. Today, an aqueduct provides access to water for crop irrigation and potable water for consumption. Previously, any water supplied at the site of the Kogi's temples had to be carried in buckets from the Jerez River at a distance of about one kilometer, and this water was not suitable for human consumption.
Now, solar panel energy powers the pump, three 2,000-liter reservoir tanks provide storage, and a filter supplies potable water, with the remainder used for agriculture. The system was designed as a low-maintenance and ecologically responsible project, and a fourth tank has now been sited at the nearby orchard. With assistance from the national government, this land was returned to the ownership and stewardship of the Kogi.
Under the Kogi's care, and through joint efforts with ACT, their sacred territory is being restored through community monitoring, trash collection, and border enforcement. Local waters are decontaminating, as indicated by studies of the health and size of populations of crayfish, a good indicator of water quality. Littoral vegetation is rebounding, and bodies of water previously scattered with refuse are being restored to beautiful freshwater lagoons.
The local population of crabs is increasing, and previously unseen semiaquatic animals such as nutrias and young alligators have been spotted. The alligators further indicate that that a recent prohibition from capturing their eggs has helped their reproduction and repopulation. Moreover, with around-the-clock control of fires, local flora is recovering across the local wetland, including propagation of marsh vegetation and young mangrove.
In addition to the return of its original state and beauty, the temple site can now fulfill its role as a gathering site for the Kogi's traditional practices—ritual offerings, internal meetings, and exchange gatherings—that strengthen their culture and advance the conservation and restoration of the local ecology.
ACT and the Kogi are grateful to a set of funders including the White Feather Foundation, March to the Top, LUSH Cosmetics, Dora Arts Janssen, and anonymous donors whose generosity made the aqueduct a reality and helped breathe new life into this ancient wetland.
