Nowadays, we buy fruits and vegetables but we do not know where they come from or how they have been grown up: if they have used any fertilized or non-authorized poison, if the workers are fairly paid, and so on. Do we know what we eat?
A good alternative is to cultivate your own orchard in your house. No much space is necessary, even if you live in a big city. Moreover, you can full your larder with products from ecological shops.
According to some studies, working with the land take you in contact with nature and benefits your health, it allows you to burn the same calories as thirty minutes of aerobics. A study conducted in 2011 in Holland, quoted in an article by CNN Health, half an hour dedicated to cultivate a garden, can significantly reduce your levels of cortisol, the stress hormone produced.

My personal experience in growing small gardens has been very positive and today I have planted several lettuce and spices and my meals are better with them. I encourage you to grow up your own orchard and enjoy it.
Unfortunately, the sea levels are rising by between 5 and 8 mm every year. This means that many countries and especially low-lying islands will no longer be habitable. As a result, the effects of global warming have already started to be visible in places such as Lohachara, an island nearby India disappeared in 1996. Its nearly 10000 residents were evacuated and they have become environmental refugees. It could be thought that this is an isolated incident but it is wrong. It is a fact that many islets have also disappeared underwater. What is more, researchers warn that several places around the world will have been devoured by rising waters in only some years. 
To sum up, I think the catastrophe can still be avoided but all countries need to work hard together to deal with the problem. Moreover, Governments should encourage the usage of renewable energies to improve the environmental conditions. Furthermore, it is really important that the deforestation of rainforests is cut down, as they are the lungs of the planet. On balance, I know it is difficult, but not impossible because it is about saving the place where we live.
