2.BIG. Do humans kill every DANGEROUS animal?

Good question.

Man is the most dangerous animal on the earth - like any other animal when they feel threatened they will kill. Man has the resources to kill so a whole species, such that they become extinct. This is a significant problem for the tiger, where man is wanting to live in areas where the tiger lives.

Without education, man would annihilate all animals - hopefully, there are enough of us who care, and will support these dangerous animals. For example the world wildlife foundation actively help these dangerous endangered species.

But even when not directly threatened they still kill - for example for sport - fishing, big game shooting, bull fighting.

4.BIG. What transport will we have in the future?

This is a BIG question

It is very dependant on the type of fuel we have available to power our transport.

If there is no oil - how would we power today's cars, buses, trains etc. Also current transport forms are not good for the planet producing CO2.

Much talk of alternative fuels - for example, using oil from plants - the problem with this is there is not enough food in the world to feed everyone so it is really not a good idea to use the food to power transport.

Hydrogen power - this gas makes up 80% of the air, + is in water - so lots of it. When used, the only exhaust is water vapour.
See http://en.wikipedia.org/wiki/Hydrogen_vehicle for more information.

Power from the sun, using the sun rays to create electricity in solar panels.
See http://en.wikipedia.org/wiki/Solar_vehicle

The target will be for transport to be designed to be lighter and faster and hopefully more fuel efficient.

Some good ideas are on:

There are a few games in this website as well.

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.
