3) Conventional methods have a bad impact on environment because they usually don't consider the quality of the soil. Monoculture, known as the plantation of one single crop for a long time and in a large area, is very harmful for the land because it takes all the nutrients from the soil, usually making it useless for future crops.
For pesticides and fertilizers, is important to understand that it doesn't only affect the plants that you want to grow, but all the nature living around the plantation. It affects the wild plants, the non-harmful insects and animals, and of course, it pollutes the soil and any water that is nearby. It also polutes the air.
The GMOS also threathen the lives of all animals and plants around the plantation. It could change the characteristics of the soil microbial population, that carries nitrogen and other essential elements. And one of the most known, it could affect human beings by eating the genetically modified food or by breathing air contamined with the GMO products.
4) To improve your health and help the environment, one of the main things you have to do is keep an organic diet. Usually organic produts are a little more expensier and sometimes they don't last as long as the regular ones, but it is a good trade when it counts to your health and estimulates farmers to keep an organic plantation to help the environment. Try keeping an eye on the label, if it says non GMO and organic, it is better for you. Usually what helps the environment and whats healthier for us goes together, because usually what comes straight from nature (if its not poisonous or anything like that) is whats best for us.
Sometime before 100 B.C., Greek sailors coming from Egypt discovered a shortcut to India. Much easier and more direct than the arduous overland route, or than hugging the deserted coastlines of Arabia and Persia for 5,000 miles, this route took only weeks to travel. Sailing straight out into the open waters of the Arabian Sea during the late spring, ships were whisked by the monsoon winds on a steady northeast course, arriving on India’s west coast by mid-summer. It was a daring feat for those first sailors who attempted it. In a time when ships rarely ventured out of sight of land, and open waters invited the prospect of drifting aimlessly at sea, it took an extraordinarily bold, unlucky, or stupid navigator to sail out into one of the largest bodies of water on the planet. Fortunately for those first crews who made the attempt, they were saved by one of the great forces of nature: the monsoon.
