The correct answer is - the change of the total volume of water in the Earth's system.
The total volume of the water in the Earth's system is pretty much the same, and for it to change, and change the levels of the water in the oceans and seas, the Earth will have to go over a totally new conditions where either a new influx of water will reach our planet, or the heat will increase and the water will evaporate, for now that is not a possibility.
The sustainable development of South America matters for the citizens of the United States because of environmental issues.
Explanation:
South America is home to the largest tropical rainforest in the world, the Amazon rainforest. This forest is nicknamed ''the lungs of Earth'', and that's because it produce the largest amount of oxygen. Not just that it produces the most oxygen, but this rainforest has the highest biodiversity, both of plants and animals.
The US citizens want the development of South America to be sustainable because they realize the dangers if the development is not sustainable. If the South American countries develop in a non sustainable manner and the Amazon forest is destroyed, the implications for the whole world would be very bad. The global temperatures will rise, the pollution will rise, and many industries will suffer because they will lose their materials.
The countries that have the biggest share of the Amazon rainforest are:
- Brazil
- Peru
- Paraguay
- Ecuador
- Colombia
- Bolivia etc.
