Solutions to the effects of global warming on water management from a geographical point of view...proposed by

Se.gif Group 1

Proposal 1

We need to find more environmentally friendly and renewable energy sources. There are plenty of new and smart ways of recieving energy. Waverollers, solar energy and other sources are all very good. They don't really affect the earth any more than just being there. The problem is using them, still, there aren't many companys that take advantage of this. Most people and most companys still use electricity from powerplants that use fossile fuels. If more people would start showing interest in more environmentally friendly power souces, more would come onto the market. Waverollers are a perfect example of brilliant engineering, but still, not awfully many are in use, since they aren't exactly cheap.


Proposal 2

Lowering the CO2 emissions on a global level. This is what has to be done during a short and a long period of time. We all have to do our best to keep the emissions low. Everything counts, even if its the tincan you recycle or taking the bike instead of the car to work. Or you could spend all your time trying to recreate the photosynthesis. By recreating the photosynthesis you can turn CO2 into oxygen the same way nature does. This way you could replace the exessive CO2 in the atmosphere with oxygen to stop global warming.


We are not going to be able to solve the enviromental crisis on a personal level though. We need global action. A very promising solution is cap and trade. This essentially sets a cap on emissions you are allowed to release. If you manage to stay below the limit, you may sell the right to emit CO2. There are quite a few upsides to this. For starters, it obviously decreases the CO2 emission on a global level, but it also comes with economical benefits. First of, it promotes enviromental thinking and rewards companies who decide to spend money on renewable energy sources. It also helps boost the economy of underdeveloped countries, as they often emit a lot less CO2 then more industrial, more developed countries.

Proposal 3

Global warming affects the Earth in many ways. Droughts for example, are one of the meteorological problems that affect plants, animals and people worldwide. Without the water in a specific region, the living around there won’t survive for long. Droughts can occur in all the climate zones from time to time, if it lasts for a long period of time it can cause severe damage. In several cases, drought can also case various environmental disasters/overall problems, such as uncontrollable fires, wind and water erosions of soil which erodes the landscape, diseases get established in a drought plant and that plants roots may rot and be to no use what so ever. These are just a few major problems that are caused by drought, and to keep this from happening in a much bigger scale we have to act now.

Things we can do about it: Desalination of seawater for irrigation or consumption when it’s really needed. Rainwater harvesting in some kind, collect and storage until drought periods. Sewage wastewater that can be treated and purified so that we can recycle it and use for irrigation. If it’s really necessary there could be a “water restriction” in some high exposed areas.
