Produce farms, rice farms and palm farms are the worst land destroyers on earth! Half of the world's population eat rice as their main stable food. Rice farms cause heavy pollution to the environment, they put out at least 11% of methane produced on earth, some estimates as high as 25% - 30%! Rice farms use 1/3 of earth's freshwater!
Commercial vegetable farms and fruit farms destroy natural habitats, they killed or chased away the original native wild life and insects. Expose the soil to the open air, let methane from inside the soil escape into the air. Tens of billions of animals have been killed by commercial produce farms. Wild life getting less and less natural habitats they can live in as more commercial produce farms created.
Palm oil is now world's most consumed edible oil, it's cheap due to large production, large areas of the natural rain forests were destroyed to make room for palm farms. Endangered Orangutans that live in rain forests are being killed, often burned alive by palm farm corporations.
Rice is not a healthy food! Despite what vegans say, most grains are actually not healthy if eaten too much, even whole grains should be eaten in small quantity due to their high carbs. High carbs are one of the top killers in humans.
Refined palm oil is a very harmful food, it causes cancer, heart and cardiovascular diseases, and many other health problems.
Ocean fish oil on the other hand is very healthy.
