Weeds are bad for the environment because they can spread their seeds really quickly and they are very hard to kill as even when they are out of the soil they can survive and sprout. Three weeds that we learnt about were Lincoln weeds, wheat and box thorn.

Humans eat weeds such as wheat, and pooh the seeds out which spread, they also keep certain weeds in their garden because it looks good but it can spread really easily. When they are out in the rural areas they can spread easily and affect natural vegetation.

Weeds are spread through wind, weather conditions, bird droppings and other animals, human clothes and shoes, tourists and shipping containers. These are the most common ways they are spread there are other ones such as people keeping them in gardens.

Weeds are not the same all over Australia as they are adapted to certain types of weather conditions. Such as the cousin to the Aloe Vera gel is adapted to survive in the rural and desert area. If they were the same all over Australia it would have to be a super weed which survives in all temperature and climates.

The weeds which are adapted to the heat will survive where as the native Australian plants will die off as they are adapted to survive in the cool and humid climates, such as in the peninsulas and bays. So it will definitely add to the weed problem around the world. They will slowly spread across Australia and take over the native plants place.

People are aware of the dangers that the weeds poses to the local vegetation in public reserves and areas. That is why they want to help weed and plant native plants. People also want to protect the local wildlife from foreign species of plants. They can also harm people because they maybe allergic to that new type of plant because they have not been introduced and built up immunity against it.


Things that we can do to help the environment include keeping weeds in contained areas. We should not keep weeds as they harm the environment, if we do keep them we must maintain by doing weeding and spraying weedicides.
