What would the world be like without dangerous animals?

This is very difficult for us to imagine, since there are many dangerous animals.

If a meat eating dangerous animal was not dangerous, it would not be able to catch its prey. As a result it would die. Eventually there would be no more meat eating animals in the world.

The world would be populated with plant eating animals. Since they would not be in danger from being eaten, more and more of these animals would populate the world.

A point could come when there was not enough food for them to eat and they to would start to die.

If animals were not dangerous to help protect their young, then the young could die. As a result
less animals would mature into adults and so the population would reduce.

What would the world be like without transport?

This is very difficult for us to imagine.

In the extreme scenario where there is NO transport.

We would have to walk everywhere - slow, would have to stay local, not go very far away on holiday etc.

We would have to carry everything we wanted. All of our food would be grown locally, just like it was for most people 150 years ago, no more food from other countries.

Everything we use would have to be found locally, for example, bricks to make houses.

Many things we take for granted would just not be available.

What will life be like when we run out of oil ? So many different types of transport we have depend on oil (petrol, diesel etc) for energy.

Why do we have DANGEROUS animals ?

They are dangerous either to:

(a) get food - hunger, catch prey
(b) to protect themselves or their young - for example hippos - they are very aggressive but do not eat meat. Kill 100-150 humans/year.

It is a way of keeping the population of some animals down
Note - just because it is dangerous to say humans - it may not be dangerous to others.

Why do we have Transport ?

We have transport, so we can move people or 'goods' from one location to another.
Man has always wanted to move
Started by walking - cheap, not very fast, can't carry very much.

Invented quicker ways to move and carry more, including:

For land - animals - horse,
Human powered - scooter, roller skates, bicycle
Mechanical power -
For Air
For Water - human powered - swimming

Also transport allows man to travel to / across places he would not normally be able to travel to/across. For example:
Boats allow man to travel across water.
Submarines allow man to travel down to great depths in the oceans.
Rockets allow man to travel in space.

Yes without transport life would be very different.
