Just like the human body requires important nutrients to survive, plants also need essential nutrients. Apart from getting these nutrients naturally, we sometimes help plants by giving them fertilisers that encourage their growth.
While chemistry has been a great benefit to us, sometimes its applications have caused harm. The widespread use of chemical pesticides and fertilizers is an example. One step towards the solution is growing more organic food.
We know that too much carbon dioxide in our atmosphere is causing climate change. If we increased forest cover on land, we could reabsorb some of the CO2. But did you know the best solution is actually in the oceans?
