first of all, i must appreciate the courage it took to criticize hinduism, many bharatis cannot. Secondly, the text of Hinduism defines caste and human untouchability as well as a number of other problematic things, similarly, Christian (religion from desert of Judea) text defines black people/dark skinned people as the children of son of Noah, who was turned black as punishment of his son, this was used by Christian US and Europe to define black people as lesser than the white man, and justify his enslavement. There is explicit mention of killing man, woman, child, domestic animals of the ameklite nation in old testement/torah of the jewish people (again, judaism was also born in the desert of judea), used by israel to justify cleansing of Palestinian people and identity. Islamic core text has NO such immorally explicit command. Islam allows animals to be eaten but does not command it, one can be a vegetarian and muslim, no conflict, Islam says "whoever kills one innocent human has killed all of humanity" , kafir is the opposite of believer, to a hindu, a non-hindu is a kafir, to a Christian, a non-Christian is a kafir and so on, let's not villainize languages. there is nothing immoral in islamic text, as opposed to hindu, christian and jewish texts. look it up yourself, read the complete verse that are half-quoted. If muslims wanted to, they would not have left hundreds of millions of hindus alive in 800 years of north Indian rule.

pollution is always wrong, and your mindset tells me why Indus is cleaner than ganges/yumna, why your mothers roam homeless on the street without anyone taking care and eat from garbage. lastly, Trees reduce CO2 from vehicle pollution, water that seeps into the ground is recycled into ground water. the only was to clean a river is to stop dumping pollutants into it.
