explain if it is okay to throw biodegradable waste in the river
Answers
All ecologies are based on a balance of living things and inorganic resources. Anything added to the environment that is not naturally occurring is going to change things. What we consider waste can in fact be a resource that local life forms appreciate, but more often than not, the quantities that we put there have mostly adverse effects.
For instance, excess nitrogen based fertilizers that wash off farm lands into the local streams, rivers, lakes and ocean contribute to excessive algae growth, throwing off the balance of life. The algae grow out of control, absorbing all the other nutrients out of the water. In many cases, instead of the extra algae providing a food source for fish, they produce toxins which kill fish and other water life. The excess algae blocks sunlight in the water from reaching underwater plants which the fish actually do eat. Finally, the dead algae sink to the bottom and decompose, absorbing oxygen and producing more toxic materials, killing more fish.
People often assume that pumping nutrients or slightly warmer water (from cooling of power plants) into rivers, lakes, oceans is automatically a good thing, but if it wasn’t there before, anything new is going to be the proverbial monkey wrench into the machine.
Biodegradable waste in small quantities might be ok, but in large quantities can feed microscopic life to grow excessively. Also, just because something breaks down by bacteria, doesn't mean that all of the products of that degrading process are harmless.
Buring biogarbage into the river you destroy both the river and deplete the soil that provides your food. Do not buy the disposable bags. The only 3 green rules are "Reduce, Reuse, Recycle". Disposing piles of bags in the river does not match any of them
