Science and facts are two completely different things. In science, there are properties that have been proven to be true like the law of gravity. However, there are many segments within science that are called theories and hypotheses. Theories and hypotheses are not facts.
For example, the theory of relativity has not been converted to a law as of yet because relativity is a property that has not been fully proven.
Scientists that work at Monsanto and Bayer have done studies on their products that claim that the weedkiller RoundUp does not cause cancer. However, there are over 40,000 concrete cases that are currently being litigated around the world showing that these people have contracted cancer from using RoundUp for a long period of time.
Do not believe the hype. Find out the facts for yourself.
