Habitat destruction is the process in which natural habitat is rendered functionally unable to support the species present. In this process, the organisms that previously used the site are displaced or destroyed, reducing biodiversity.[1] Habitat destruction by human activity is mainly for the purpose of harvesting natural resources for industry production and urbanization. Clearing habitats for agriculture is the principal cause of habitat destruction. Other important causes of habitat destruction include mining, logging, trawling and urban sprawl. Habitat destruction is currently ranked as the primary cause of species extinction worldwide.[2] It is a process of natural environmental change that may be caused by habitat fragmentation, geological processes, climate change[1] or by human activities such as the introduction of invasive species, ecosystem nutrient depletion, and other human activities mentioned below.
you're just throwing out terms as so many environmentalists love to do without understanding that the Earth is an ecosystem that continually evolves. digging a hole in the ocean or lighting a tire on fire is a huge deal to you but to the earth it's not even a registered nuisance as it's been through volcanoes, quakes, asteroids, hurricanes, and nuclear explosions. folks like you that carry the ego that the earth even cares of our presence are a joke to me...such small way of thinking. likely one day a massive asteroid field comes down and blows us all to shit but you know who will carry on just fine? the earth
Human impact on biodiversity is significant, humans have caused the extinction of many species, including the dodo and, potentially, large megafaunal species during the last ice age. Though most experts agree that human beings have accelerated the rate of species extinction, the exact degree of this impact is unknown, perhaps 100 to 1000 times the normal background rate of extinction.[57][58] Some authors have postulated that without human interference the biodiversity of this planet would continue to grow at an exponential rate.[1]
Human impact on coral reefs is significant. Coral reefs are dying around the world.[59] In particular, coral mining, pollution (organic and non-organic), overfishing, blast fishing and the digging of canals and access into islands and bays are serious threats to these ecosystems. Coral reefs also face high dangers from pollution, diseases, destructive fishing practices and warming oceans.[60] In order to find answers for these problems, researchers study the various factors that impact reefs. The list of factors is long, including the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, biological virus, impacts of dust storms carrying agents to far flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal areas.
General estimates show approximately 10% world's coral reefs are already dead.[61][62][63] It is estimated that about 60% of the world's reefs are at risk due to destructive, human-related activities. The threat to the health of reefs is particularly strong in Southeast Asia, where 80% of reefs are endangered.

These are simple terms being used in this thread. And yes the earth is giant and is always adapting. It's not as resilient as you make it out to be but it is resilient. That's not the issue of this thread through. The issue of this thread is have humans had ANY NEGATIVE effect on the earth. And I think it's already clear. Even If you think it's overblown and the earth will be fine. Humans are having at least some negative effects
Negative effect:
It's official: The extinction of the dinosaurs and a host of other species 65.5 million years ago was caused by a massive asteroid that crashed into the Gulf of Mexico, creating worldwide havoc, an international team of researchers said Thursday.
The 7.5-mile-wide asteroid was traveling at a speed about 10 times that of a rifle bullet when it hit, releasing a billion times more energy than the Hiroshima atom bomb. The impact blew dirt and rock around the world, set massive wildfires, knocked down forests worldwide, triggered massive tsunamis and earthquakes of magnitude 11 or larger and even caused parts of the continent to slip into the ocean.
Those events wiped out more than half of all species on Earth in what has been called the greatest extinction event of all time. The species lost included not only the dinosaurs, but also the bird-like pterosaurs, large marine reptiles and many smaller land and sea creatures, clearing the way for the emergence of mammals as the dominant life form on the planet.

Yet here we are with a life expectancy closing in on 80.
You can't even define how dumb the poster who started this thread actually is.
