Tar Sands Article 

1. They said the risk of spills is increasing. This leak would be more devastating than a crude oil leak. Taking, transporting, and refining tar sands crude also needs much more water and energy than conventional crude.

2. It could ruin our drinking water.

Fracking 

Would I be okay with someone coming next to my house and start fracking up everything? I think the most obvious answer after watching what the pros and cons of fracking are would be no. No one wants that next to their house. Even if fracking creates jobs and decreases dependence on foreign oil it still ruins the area where it is placed. We know that fracking is what gets us our oil to heat up our houses and lots of other good stuff, but we also know that we can't use it forever. It is too bad that our houses are everything is still dependent on fossil fuels, and even though new solar technology is coming out, it is very expensive. Money seems to be the source of anything changing. Back to the topic of fracking, there are way more cons than reasonably reasons. If they started fracking near your house, it would be bad for you but the source of oil for everyone else. So, it is kind of like you are the "sacrifice" for everyone else. Maybe the real question is, would you sacrifice your water supply for everyone else to have energy? I like having my nice clean water so I would have to say no, I'm not that generous. I don't know what I would do if I didn't have running water. It is one of the basic needs so it isn't fair that a group of people would just take that away from you. In conclusion, I would not say yes to anyone fracking near my home.

Hydraulic fracturing is when they use liquid at a high pressure to forcefully remove stuff to create space, especially for extracting oil and gas.

People oppose it because it is dangerous and it is very polluting.

2. Countries that use the most coal:

Seawall! 

Description:  a man-made wall that has a purpose to keep sea waves from getting up onto land.

 Disadvantages: The waves hit the seawall upwards and downwards. The downwards hit moves the sand and the water moves down the seawall, causing it to create the area before the seawall to have a downwards slope.

Strip Cropping

What it is: Strip cropping is done by putting different crops next together in strips because of the amount of water and fertilization another one needs. If there was one crop that needed a lot like corn and wheat, it would die faster because of taking too much for itself. They plant crops that do not need these as much like alfalfa, with crops that take a lot, so one can create a barrier to keep it even and balanced.
