Answer:
Reduce
Reducing waste is the most important thing we can do. By reducing waste, we avoid the unnecessary use of resources such as materials, energy and water. It means there is less waste to manage.
How can we reduce waste?
Buy in bulk to reduce packaging
Take a reusable shopping bag with you so you don't have to use a paper or plastic bag from the shop
Say ‘no’ to a plastic shopping bag when you only have a couple of items
Choose products that use less packaging
Buy reusable items rather than disposable ones
Stick a "no junk mail" sign on your letter box
Take your lunch to school in a reusable container.
Reuse
The next most important thing we can do is reuse waste material. That way it doesn't go in the rubbish and end up in the landfill. It also means you don't have to buy a new product. That saves you money and saves the energy and resources that would have been used to make the new product.
How can we reuse waste?
Give unwanted toys and books to hospitals or schools
Put unwanted clothes in used clothing bins
Use plastic containers for freezing or storing food items
Save wrapping paper and boxes to use again
Use old jars for storage
Take old magazines to your local doctor's or dentist's surgery
Shop at second hand stores or use online trading websites to buy items that are unwanted by others
Take household items to your council’s resource recovery centre
Make memo pads out of waste paper
Re-use envelopes - purchase reuse labels.
Recycle
Recycling involves some form of reprocessing of waste materials to produce another product. For example, recycling plastic bottles to make buckets.
What can be recycled?
The main products that can be recycled are paper, cardboard, glass, aluminium, tin and plastic containers.
Composting and worm farms are methods of recycling organic waste.
Buy recycled
You can buy products that are made from recycled materials. This is called ‘Closing the Loop’.
Recycling in your district
Different districts collect different recyclables at the kerbside and at their transfer stations/resource recovery parks. Contact your local city or district council to find out what they collect.
Recover
This is the recovery of waste without any pre-processing. For example, waste oils that cannot be refined for reuse in vehicles can be burnt for energy recovery. Recovering the energy from waste oil reduces our dependence on coal and imported oil.
Residual Management
This is the last option when waste cannot be used in any other way. Usually, this means sending rubbish to a landfill. Residual disposal of liquid waste is normally into a sewer or septic tank.
It is very important to manage residual solid and liquid waste properly. Waste not disposed of correctly can cause damage to health and the environment.

At certain intervals, the ovaries release an ovum, which passes through the Fallopian tube into the uterus. If, in this transit, it meets with sperm, a single sperm (1-cell) can enter and merge with the egg or ovum (1-cell), fertilizing it into a zygote (1-cell).
Fertilization usually occurs in the Fallopian tubes and marks the beginning of embryogenesis. The zygote will then divide over enough generations of cells to form a blastocyst, which implants itself in the wall of the uterus. This begins the period of gestation and the embryo will continue to develop until full-term. When the foetus has developed enough to survive outside the uterus, the cervix dilates and contractions of the uterus propel the newborn through the birth canal (the vagina).
The corresponding equivalent among males is the male reproductive system.
