I think you should apply the style to the List item -
li.list{position:absolute;left:100px;width:100%;padding:0;margin:0;list-style-type:disc;font: 900 15px arial;color:#996600;}
Then in the body:-
<ul><li class="list"> Road accidents</li><br><li class="list"> Habitat destruction - urban development</li><br><li class="list"> Dog and cat attacks - be responsible with your pets</li><br><li class="list"> Disease - adverse weather conditions</li><br><li class="list"> Flying into windows</li><br><li class="list"> Poisons in the environment -many household substances are toxic to wildlifeeg. fly spray, herbicides</li></ul>
