As the global population rises, so does the demand for food. This in turn increases the agricultural cow population, which has been contributing to green house gasses due to their methane production. This methane production is potent and has been adding to the greenhouse effect.
The added greenhouse effect increases the heat trapped inside the earths atmosphere. This affects plant life as well as water evaporation rates.
Can a food source be developed for cows that will reduce or eliminate their methane production?

There is a mass of garbage floating in the pacific ocean, which has begun to distress environmentalists. Most of the garbage is undetectable to the human eye because it is broken down plastic. This heap of garbage is growing and negatively impacting the environment.
Many animals are dying because they are mistaking the garbage for food and consuming it. Also, the break down of plastic releases toxins into the area, harming all wildlife.
How can this mess be cleaned up?

The greater Houston area depends on waste water from north Texas to supplement its water supply. Though, north Texas cities are starting to recycle and reuse their own waste water, in preparation for another drought. This may cause an even more damaging dry spell to Houston. 

If Houston looses that much of its water supply, local plans will die due to lack of water. This mass death of vegetation will increase erosion of land as there will be nothing to hold it down- changing the landscape. 

Will Houston be able to recycle it's own water waste?
