Hi! We created this blog because our English teacher suggested it to us in English class. This year we have a new member and with him we hope to make our blog better. And, as our English teacher says: "A smile goes a long way!"

GMF
- Crops can be genetically altered to resist to pests, so they need less pesticide and they resist more to climate changes;
- Increase massive production;
- Growth of "perfect living beings";
- Their nutritional value can be altered to satisfy the hunger in poor continents, like Africa and in some parts of Asia.
But GMF can have some disadvantages too, like:
- GMF can cause some allergies;
- Crops can be affect by a disease that they can not fight because in the genetic modification they lost genetical variety so they don't have power to fight the disease so it causes massive destruction of the crops;
We don´t know what are the risks of the comsumption of the GMF and the risks to the enviorenment.
GM food is a new so scientists have a short space of time to test it and say if it is good to consume or not . Probably just a few years latter we will know if it is safe or not.

Recycling
Everyday, all around the world, people consume a lot of products and do a lot of trash. This trash could be recycled or not. The best thing to do is to recycle. In America, after having collected the trash, it is separated by types -paper, plastic, glass, metal and comom trash. The trash that could be recycled go to a special machine that "pack" it and then it is transported to other places where it is recycled. The trash that can't be recycled goes to a landfill where it is squashed, to remove the air and make the trash good to build on (because there are some explosive gases that obviously are dangerous), and covered with earth. A landfill can originate fields for other purpuses, so landfills can be reused after having all the trash. The trash produces methane gas that is harvested by wells, feeds a gas turbine and produces electricity and that gas can be used to fuel, for example, the garbage trucks too. So trash have a cicle, it produces fuel to fuel garbage trucks so that they can collect more and more trash.
So, with this we can see that recycle and reuse waste for other purpuses is possible and better to the environment. If America does this why doesn't other countries do it too? Think about it: after "packaging" the garbage it is worth a lot of money so it could also solve some economic problems and the world will be better if everybody recycle and every country helps people to do it. Imagine a world without trash spread in the nature and green places where the electricity of our homes is produced from trash gases and where the fuel of our cars is "produced from trash". Imagine a total green world where it is better go out than staying at home watching TV.
