there would be cleaner fire hydrants, no barking in the background, no watching where you step in the park, but no best friend
and also less love and it would be more dangrous outside because there are people out there that will want to hurt you and the dogs are your only hope ! !

we would all be eaten by flies
it will definitely affect the humans and all human settlements. Rather all the elements in the ecological chain has has its impact on each other. Take an example, if all lions dies, what will happen? the vegetarian wild life will grow at a speedy rate endangering the existence of forests and later may move to cultivations made by humans destroying it and making humans suffer for want of food. trees in the same line, if gets exhausted, will impact on human settlement in-terms of low rains, soil erosion, fast degradation of underground water streams etc. There's no limit to what can happen to human. All your imagination in this regard will happen to humans if all trees died.
We would have all died
Taking out the largest group of animals on earth from an ecosystem would most likely destroy it. Insects outnumber humans I believe 100 to 1 if not more.
First, all of the plants and trees would die. Then all the animals, including humans; would die.
If all the seahorses died the crabs, tuna, and penguins would have to find another source of food.
You would fart all over a cat and it would get pink eye
If all plants died, humans would be severely affected due to the loss of oxygen production and the collapse of food systems. Plants are crucial for photosynthesis, which generates the oxygen we breathe and absorbs carbon dioxide. Additionally, the extinction of plants would lead to the collapse of ecosystems, disrupting food chains and eliminating sources of nutrition for humans and other animals. This would ultimately result in widespread famine and ecological disaster, making survival extremely difficult.
The earth will freeze to temperatures extremely low and the humans will al die,but don't sweat it's not going to happen in till 5 billion (5000 million) years.
nothing
From nausea and vomiting, all the way to death.
we would die, too
